ATo'MIzEE BURNER.

Application led May `10, 1921. Serial No. 468,318.

To all whom 'it may concern.'

Be it known that I, CHARLES LINKE, engineer, citizen of the FrenchRepublic..residing at Paris, Department of the Seine, in France, andhaving P. O. address 10 Rue Jean Jacques Rousseau, in the said city,have invented certain new and useful Improvements in or Relating toAtomizer Burners; and I do hereby declare the following to be a full,clear, and exact. descriptionof the invention, such as will enableothers skilled in the'art to which it appertains to make' and use thesame.

Burners actually in use such as mechanical atomizing burners or blastburners are subject to the following inconveniences. The first classcommonly require high pressure, careful filtering and an almost absoluteuniformity of the temperature required for preheatin the combustible.The second type ordinari y require an auxiliary motive force which isout of all proportion with the result obtained.

The present invention has for its object an atomizing burner whichpermits of the delivery of the combustible to the burner withoutpressure and which requires during the atomization a power comparativelysmall relatively to that developed by the burner. The action of thepresentburner is based on the effect of mechanical `attenuation producedon the combustible which is fed in a continuous manner on to a memberadapted to be rotated at a high speed and provided, if desired, withgrooves or recesses or suitable vanes. I

The particles of combustible which in their trajectory meet with noobstacle when projected into the furnace through the escape orifice ofthe burner are projected in Vthe form of a fine 'spray or mistparticularly suitable for rapid combustion. The apparatus is providedwith an arranglement for the recovery of such portion of t e liquid asis errantly projected against the interior walls of the apparatus andthe feed of fresh combustible is effected through an orifice capable ofmovement concentrically to the aforesaid member, thusrensuring aprojection, in which the direction of the jet can be controlled andregulated as desired.

' 1n order that the invention may be clearly understood reference ismade to the accompanying drawing which shews several constructionalforms of burner in accordance with the present inventlon.

Figure 1 is a section of a disc-atomizer.`

prises a disc-wheel 1 driven by a pulley 2,

the combustible being admitted thereto by a passage 3 and a tube 4. Thecombustible falls onto the wheel 1 rotatable at high speed and isprojected therefrom in an atomized condition through the opening 5. Thelower part of the apparatus is in the form of a sump 6 so as to ensurethe concentration or collection of the non-atomized liquid which isdrawn through the passages 7 in the disc- -wheel 1, which atomizes theliquid and reprojects it.

Figure 2 shews the application of a discatomizer to a circular burnerfor round Yboilers for a central heating or cooking burner, etc. Thedisc-wheel 1 is mounted on a tube 14 which receives its rotary movementfrom a pulley, not shown, situated be-l low and is supported on astandard 15 provided with a ball race 16. The feed tube 17 for thecombustible passes through the tube 14 and carries at its upper end atube 18 which directs the combustible upon the wheel 1. The apparatusis/completed by a cast iron hood 19 to which is secured the feed tube17, a wing nut 20 permitting of the tube 18 being set in any desireddirection. The atomized liquid is projected through the space 21provided between the lower part of the hood 19 and the upper edge 22 ofthe body of the apparatus. The non-atomized liquid passes through therotatable tube 14 and4 yis fed anew through the tube 17 onto the wheel1.

Figure 3 shews the same arrangement but with two disc-wheels 1, 1 whichensure regularity of working and a greater' output.

Figure 4 shews an atomizer comprising a wheel 8 provided with vanes 9and an adjustable spraying guide 10. The errantly projected liquid isrecovered through the passage 11'.

In Figure 5, the atomizer comprises two Vaned wheels 8, 81, the lowerwheel ensuring the recovery of the errantlywprojected liquid. Of thevarious structural modifications of the above apparatus, mention may bemade of the use and injection of steam at any suitable point in order toeffect rotation of the vaned wheels and at the same time to assist inthe spraying of the combustible. Such a construction with an injectiontube 23 is shewn in Figure 5.

In the arrangement shewn in Figure 6, the feed of the combustible iseffected through a passage 12 and a spraying guide 13 and the vanedywheel 8 is so situated as to ensure the recovery of the errantlyprojected liquid.

Claims: Y

1. In a Vliquid fuel burner the combination of an elementrotary on avertical axis and adapted on rotation to project centrifw of a rotarinse-,35e

gally from its periphery and in attenuated form liquid fuel fed., to it,a receptacle for liquid fuel arranged beneath said rotary element, thearrangement being such that the said rotary element in its lower partmay lbe immersed in liquid contained in said receptacle, said rotaryelement being further provided with a passage extending upward withinsaid rotaryl element r`'and opening below within said receptacle andopening above to a surface over which on rotation liquid will flowcentrifugally.

2. In a liquid fuel burner the combination element adapted to throw infinely divi ed formcentrifugally from its surface liquid vfuel fed toit,and a member` arranged adjacent said rotary element and adjustablerelatively. to said rotary element and by virtue of such adjustabilityadapted to regulate the quantity of fuel so centrifugally thrown fromthedisk.

In testimony whereof .I ax my signature.
